865 Decimal in Binary

Let's convert the decimal number 865 to binary without using a calculator:

Step 1: Divide by 2

Start by dividing 865 by 2:

865 ÷ 2 = 432 (Quotient) with a remainder of 1

Step 2: Divide the Quotient

Now, divide the quotient (432) by 2:

432 ÷ 2 = 216 (Quotient) with a remainder of 0

Step 3: Divide the Quotient

Now, divide the quotient (216) by 2:

216 ÷ 2 = 108 (Quotient) with a remainder of 0

Step 4: Divide the Quotient

Now, divide the quotient (108) by 2:

108 ÷ 2 = 54 (Quotient) with a remainder of 0

Step 5: Divide the Quotient

Now, divide the quotient (54) by 2:

54 ÷ 2 = 27 (Quotient) with a remainder of 0

Step 6: Divide the Quotient

Now, divide the quotient (27) by 2:

27 ÷ 2 = 13 (Quotient) with a remainder of 1

Step 7: Divide the Quotient

Now, divide the quotient (13) by 2:

13 ÷ 2 = 6 (Quotient) with a remainder of 1

Step 8: Divide the Quotient

Now, divide the quotient (6) by 2:

6 ÷ 2 = 3 (Quotient) with a remainder of 0

Step 9: Divide the Quotient

Now, divide the quotient (3) by 2:

3 ÷ 2 = 1 (Quotient) with a remainder of 1

Step 10: Final actions

The Quotient is less than 2 (1), so we will transfer it to the beginning of the number as a reminder.

Step 11: Write the Remainders in Reverse Order

Now, write down the remainders obtained in reverse order:

1101100001

So, the binary representation of the decimal number 865 is 1101100001.
